AWNING-ARM.

Application filed July 1, 1910, Serial No. 569,903.

To all whom it may concern:

Be it known that I, FREDERICK A. ANTON, a citizen of the United States, and a resi dent of the city of Topeka, in the county of Shawnee and State of Kansas, have invented new and useful Improvements in Awning-Arms, of which the following is a speci fication.

In Patent No. 986,120, granted to me March 7, 1911, I have shown and claimed certain features herein shown but not claimed.

My present invention relates to the class of awning arms and awnings shown in that application.

The object of my present invention is to simplify and strengthen the said awning arm, and to improve upon it generally; to provide a simple and efficient means for preventing the arm from locking when folded; to provide for making the arm out of certain castings and straight steel bars; to make certain cast brackets which are of peculiar form; and to provide the parts, improvements, and combinations herein set forth and claimed. And my invention comprises the parts, improvements, and combi' nations herein set forth and claimed.

In the drawings accompanying and forming part of this specification, and in the description of the drawings, I have shown and described my invention in its preferred form, and have shown what I deem to be the best mode of applying the principles thereof; but it is to be understood that the invention is not confined to the details of such drawings and description, and that I contemplate changes in form, proportions, and materials, the transposition of parts, and the substitution of equivalent members, within the scope of the appended claims, without departing from the spirit of my invention.

Figure 1 is a side elevation of an extended awning arm made in accordance with the principles of my invention with sections of the roller, the awning fabric, the curtain, and the pole; also showing in dotted outlines the positions of the fabric, pole, the curtain, and the outer end of the arm when the awning is rolled up on the roller and the arm folded back. Fig. 2 is a plan view of the awning arm with a portion of the poles secured to the outer end of the arm. Fig. 3 is a sectional elevation of the bracket which is secured to the building for supporting Specification of Letters Patent.

Renewed November 17, 1913. Serial No. 801,550.

the arm, the plane of the section being indicated by the line 3 in Figs. 1 and 4. Fig. 1 is a vertical sectional elevation of said bracket on a plane indicated by the line 4 in Fig. 3. Fig. 5 is a plan view of the adjustable bearing whereby the adjusting of the dip of the arm is accomplished. Fig. 6 is a detached view of the inner hinge member of the arm. And Fig. 7 is a longitudinal sectional view of the bracket which is secured to the pole and to which the outer end of the arm is pivoted. Fig. 8 is a front view of the inner hinge member shown in Fi 6.

imilar reference characters indicate like or corresponding parts throughout the several views.

10 is a bracket adapted to be secured to the front of a building at the top of the window to be protected by the awning as by the face-plate 11 and bolts or lag-screws passing through the several holes 12, 12. The bracket has a lower arm 13 with a hole 141 therein and an upper arm 15 with a slot 16 therein, and the two arms are connected and the bracket suitably reinforced by the webs 17, 17, 18.

19 is a bearing block having therein a hole 20; and 21 is a bolt extending through said hole and the slot in the upper arm for clamping the block securely to the upper arm at any point permitted by the length of the slot, and a washer 22 is preferably provided between the slot and the head or nut of the bolt. It will be noted that the face of the upper arm to which the block is clamped describes an are on a radius extending from the hole 14 in the lower bracket arm, and that by shifting the block inwardly or outwardly the hole 14 in the lower arm and the hole 14 in the block may be disposed at various angles to the line of the face plate or building. It will also be noted that the line between these two holes is inclined outwardly from the bottom up, and also laterally (sec especially Fig. 3) from the bottom up. The awning arm bracket herein described forms the subjectmatter of another application, Serial No. 723,872, filed by me October 4, 1912. 23 is the inner hinge member for the arm and has, preferably formed integrally with t, a pin 21-, which is adapted to bear in said holes 14: and l t; and this pin is preferably secured in the two lugs 25, 25 of said hinge member. This member is also of the special form indicated in the drawings, with its side face 26 inclined at such an angle that when the member is secured in its bearings, this face will incline laterally at an angle opposite to the angle of incline 0f the pin 24. Secured to this oppositely inclined face are the two steel bars 28, 23, whose outer ends are secured to one member of the middle hinge, this memberbeing indicated by the numeral which has an offset pivot or hinge hearing 30, to which is secured the other middle hinge member 31, by means of a bolt or pin 32. This pin is not parallel with the pin 24, but is inclined laterally at an opposite angle thereto and also at a slight angle outwardly (relatively speaking) from the bottom up. The member 29 has a projection 50 which engages against the member 31 to prevent the hinge from turning farther than to the place where the projection 50 comes against the member 31, for a purpose hereinafter explained.

33 is a steel bar secured to the member 31 and extending out therefrom at a relatively upward angle to theiline of the bars 28, 28, and secured to its outer end is a casting 34- with an offset 35 pivoted to the lugs 36, 36 of the bracket 37 by means of a pin or bolt 38. This bracket has a longitudinal slot 39 and a screw-hole 40 by which it may be secured to the awning pole 41 by the bolt 42 and screw 43, respectively.

44 is the roller, suitably mounted just above the brackets and provided ordinarily with means for turning it so as to draw up the awning canvas and roll it thereon, in the manner common with other types of awnings and not necessary to be herein shown or described.

45 is the awning fabric, such as canvas, extending from the roller to the pole, and extending down outside the pole in the form of a curtain 46.

By reference to Fig. 2, which shows the arm extended full length, it will be noted that the offsets in the several castings or hinge-members are so arranged that the middle pivot cannot come in line or in or beyond the dead center with the end pivots 24 and 33, because of the fact that the stop 50 prevents it. Vere it not for this or some equivalent stop, the arms might be folded in either direction, either to the right or to the left. By rolling up the awning, and thereby pulling inwardly (in the direction of the arrow (30) the pressure on the outer end of the arm will cause the middle hinge to travel in the direction of the arrow 61; and by continuing thus to roll up the awning, the arm will be folded up substantially parallel with the pole, roller, and front of the building with the pole, awning fabric, curtain and bracket in the positions inclicated by the dotted outlines 41, 45, 46', and 37, in Fig. 1; and in this position the fabric and the curtain protect the arm both from the weather and from the view.

Preferably the lateral angle of the pin 32 is less than the outward angle of the pin 24, so that when the arm is folded the pin 32 will angle outwardly from the bottom up; so that when the arm is folded, all parts will tend, by the force of gravity, to swing outwardly. Obviously the force of gravity tends to swing the inner arm outwardly to a line beyond the position permitted by the stop 50, and also tends to swing the outer arm beyond the position permitted by the stop; and, with the added weight of the pole this tendency is very decided, thereby insuring the full extension of the arm when the roller is turned to unroll the awning fabric.

To give the awning the proper dip to adapt it to any particular building, the block 19 is shifted and secured in proper position by means of the bolt 21, as heretofore described.

As described in my said previous application, these arms are preferably used in pairs, a right and a left; one foldinglaterally to the right, and the other folding laterally to the left, whereby with the awning fabric and the pole, there is assured a straight line of travel inwardly and outwardly of the pole and outer pivots 38, 38.

The purpose of a relatively upward incline of the bar- 33 is to lift the main body of the awning fabric 45 above the arms; otherwise the awning would sag down on said arms and not only interfere with their operation but also tear or rain the canvas; with this arrangement, however, the canvas does not come in contact with the arms.

For reasons of economy, lightness, strength, and durability, the brackets and binge members are made preferably of malleable iron, and the bars 28, 28, 33 are straight steel bars.

The purpose of having the slot 39 is so that the bracket may be first properly placed on the pole, the bolt drawn tight, and then the other end screwed down.

The outer hinge member 34 is provided with a rib or projection 65 which is adapted to bear against the awning pole when the arms are folded up. This has the effect upon the steel rods of springing them and thereby tending, when the awning arm is folded up, to force the middle hinge member inwardly and the pole and outer hinge outwardly, thus preventing the middle hinge from swinging outwardly first and locking the arm.

What I claim is:

1. An awning arm comprising two sections pivoted together at their adjacent ends, the inner end of the inner section being pivoted to a frame and the outer end of the outer section being pivoted to an awning pole, the inner end pivot and the middle pivot being disposed at an angle outwardly from the bottom up and being inclined laterally in opposite directions, the outward incline being greater than the lateral inclines, the outward incline of the middle pivot being less than the outward incline of the inner end pivot.

2. An awning arm comprising two sections pivoted together at their adjacent ends, the other end of the inner section being-pivoted to a frame and the other end of the other section being pivoted to an awning pole, the pivots being so disposed that the sections are fold-able together laterally, the middle pivot being tilted at a lateral angle to the inner end pivot, and the outer section being provided near its outer end with a projection adapted to bear against the awning arm when the arm is folded together.

3. An awning arm comprising two sections pivoted together, the other end of the outer arm being adapted to be pivoted to an l l l l awning pole, and the other end of the inner member being adapted to be pivoted to a frame, the outer member being formed with a projection which bears against the awning pole when the arm is folded.

4. In combination, a frame, an awning pole, and two arms foldable laterally and pivoted together, the outer end of the outer member being pivoted to the pole, and the inner end of the inner member being pivoted to the frame, and the parts being so arranged that the outer arm bears against the pole at a point near its outer end when the arm is folded.

In testimony whereof, I have signed my name to this specification in the presence of witnesses.
